Date: Wed, 30 Dec 2020 09:43:29 +0800 From: Zheng Yongjun <zhengyongjun3@...wei.com> To: <davem@...emloft.net>, <kuba@...nel.org>, <netdev@...r.kernel.org>, <linux-kernel@...r.kernel.org> CC: <Markus.Elfring@....de>, Zheng Yongjun <zhengyongjun3@...wei.com> Subject: [PATCH v2 net-next] net: kcm: Replace fput with sockfd_put The function sockfd_lookup uses fget on the value that is stored in the file field of the returned structure, so fput should ultimately be applied to this value. This can be done directly, but it seems better to use the specific macro sockfd_put, which does the same thing. The refactoring proposed was found using the following semantic patch. // <smpl> @@ expression s; @@ s = sockfd_lookup(...) ... + sockfd_put(s); - fput(s->file); // </smpl> Signed-off-by: Zheng Yongjun <zhengyongjun3@...wei.com> --- net/kcm/kcmsock.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/net/kcm/kcmsock.c b/net/kcm/kcmsock.c index 56dad9565bc9..a9eb616f5521 100644 --- a/net/kcm/kcmsock.c +++ b/net/kcm/kcmsock.c @@ -1496,7 +1496,7 @@ static int kcm_attach_ioctl(struct socket *sock, struct kcm_attach *info) return 0; out: - fput(csock->file); + sockfd_put(csock); return err; } @@ -1644,7 +1644,7 @@ static int kcm_unattach_ioctl(struct socket *sock, struct kcm_unattach *info) spin_unlock_bh(&mux->lock); out: - fput(csock->file); + sockfd_put(csock); return err; } -- 2.22.0
